Sky UE5 materials

Sky and atmosphere materials sit at the edge between shader work and scene direction. They can be simple gradient domes, cloud layers, star fields, aurora effects, fog cards, or stylized horizon treatments. The strongest graphs expose color ramps, height or view-angle masks, panning cloud detail, and emissive controls without hiding the composition behind one opaque texture sample.

This category is useful for materials that create mood rather than surface detail. A sky graph might drive a full-screen background, a mesh dome, a billboard cloud, or a world-space fog plane. Because these materials often frame an entire scene, small parameter changes matter: horizon contrast, sun-side tint, cloud softness, and night-sky intensity should be easy to find. Lightweight graphs that artists can paste into a prototype are especially valuable here.
